fix(app): keep square logos out of loading screens

[waleedlatif1]

Summary

• Use only the configured wordmark on application loading screens. A square brand logo no longer replaces it.
• Fall back to the canonical Sim SVG when the brand name remains Sim, or the custom brand name otherwise. Preserve explicit custom wordmarks, shared color tokens, and loading behavior.
• Document the distinction between loading wordmarks and square logos.

Type of Change

• Bug fix

Testing

Reproduced the square-logo fallback through the running app with a disposable PostgreSQL fixture before the fix. Seven HTTP streaming cases cover default branding, square logos, custom names, explicit wordmarks, and color-only branding. Browser checks cover light/dark at 360, 768, 1440, and 2560 px widths, loading-to-ready, and Files navigation; JSON reports and screenshots saved locally. Signed-out and access-denied checks pass.

All eight applicable cleanup passes, 6 adjacent tests, full root tests (including 36,998 app tests), lint, all 26 workspace type checks, 59 repository audits, generators, block registry, docs manifest, and actionlint passed. No test source changes. An unchanged route-inventory test hit a timeout in the first full run; its isolated run and the complete retry passed unchanged.

[Medium impact] The PR appears safe to merge; the loading fallback matches the stated branding behavior.

Summary

Loading screens now use only the configured wordmark, not the square logo.

• Loading screens show wordmarks instead of square brand logos.

waleedlatif1 explicitly requested the built-in Sim wordmark for square-logo-only or color-only branding when the brand name remains Sim.
